-==L=a=N=c=E==- Forums Junkie Location: Brisbane, Queensland Registered: January 2004	Re: GT4 cutting out Wed, 04 August 2004 20:26 As someone on here has already stated. Go and get yourself a boost gauge. You can pick up spitfire boost gauge (-30Hg, 20PSI) for around $85 at autopro. To fit is very easy, find yourself a vacuum source (there is a handy spare vacuum port behind the back of the intake, near the 'O' of the toyota symbol). Plum it in there and feed the line thru the firewall into the cabin. It can be temporary if you want, but it woudl be an idea to install one now. At idle you should be around the 18-20Hg mark. This is considered normal, any lower, and you have a possible vacuum leak (14Hg). Apart from that, go for a drive and watch the gauge carefully. If you are running stock boost, it should be around 7PSI. Also, if the Turbo VSV (ECU boost controller) is still connected, in the lower gears you will only take around 4-5PSI. This is normal. Now watch the gauge carefully, as your coming onto boost, if you see it spike (you'll know it, when the gauge tries to boost beyond 12psi) then you will hit boost cut, and you know what that is already. As spectral has said earlier, your going to have to find out where its coming from. If it is overboosting, then it will be a wastegate issue. If it isn't, then it would be a MAP sensor problem. Getting to the wastegate is easy, all you have to do is remove all the intake plumbing. Once your there, check that the line from the compressor housing to the wastegate is in good condition, if it isn't then replace it. Check to see if the wastegate will open smoothly by hand, if it isn't, then i'd suggest getting that looked at by the pros. Also while your down there, you might as well disconnect the Turbo-VSV line (the line that runs from the wastegate into the engine). But don't do that until you figure out your overboost problem.
